Itomography ebunjiweyo yolukakayi luvavanyo olwenziwa kwisixhobo kwaye luvumela ukuxilongwa kwezifo ezahlukeneyo, ezinjengokubona ukubetha, i-aneurysm, umhlaza, isifo sokuwa, i-meningitis, phakathi kwabanye.

Ngokubanzi, i-cranial tomography ihlala malunga nemizuzu emi-5 kwaye ayibangeli zintlungu, kunye nokulungiselela uviwo kulula.

Yenzelwe ntoni

Itomography yecomputer luvavanyo olunceda ugqirha ukuba abhaqe izifo ezithile, ezinje ngokubetha, isifo se-aneurysm, umhlaza, i-Alzheimer's, iParkinson's, multiple sclerosis, isifo sokuwa, i-meningitis, phakathi kwabanye.

Yazi ezona ntlobo ziphambili zetompography.

Luqhutywa njani uviwo

Uviwo lwenziwa kwisixhobo, esibizwa ngokuba yitamatografi, emile okwejingi kwaye ikhupha i-X-ray edlula kwikakayi kwaye ibanjwe iskena, ebonelela ngemifanekiso yentloko, ethi ke ihlahlelwe ngugqirha.

Ukuze umntu avavanywe, kufuneka akhulule kwaye anxibe igawuni kwaye asuse zonke izixhobo kunye nezinto zentsimbi, ezinje ngezacholo, iwotshi okanye iinwele, umzekelo. Emva koko, kuya kufuneka ulale ngomqolo etafileni eya kuthi ityibilike kwisixhobo. Ngexesha loviwo, umntu kufuneka ahlale engahambelani, ukuze angonzakalisi iziphumo, kwaye kwangaxeshanye, imifanekiso iyenziwa kwaye igcinwe kugcino. Kubantwana, i-anesthesia ingafuneka.

Uviwo luhlala malunga nemizuzu emi-5, nangona kunjalo, ukuba kusetyenziswa umahluko, ixesha lide.

Xa uvavanyo lwenziwa ngokuchaseneyo, imveliso eyahlukileyo itofwa ngqo kumthambo wesandla okanye ingalo. Kolu viwo, kuvavanywa isimilo semithambo yezakhiwo phantsi kohlalutyo, esisebenza ukugqibezela uvavanyo lokuqala olwenziwa ngaphandle kokuthelekisa. Bazi ubungozi bovavanyo olwahlukileyo.

Ungazilungiselela njani iimviwo

Ngokubanzi, ukuthatha uvavanyo kuyimfuneko ukuzila ukutya ubuncinci iiyure ze-4. Abantu abathatha amayeza bangaqhubeka nokuthatha unyango ngesiqhelo, ngaphandle kwabantu abathatha i-metformin, ekufuneka iyekwe ubuncinci iiyure ezingama-24 ngaphambi kovavanyo.

Ukongeza, ugqirha kufuneka aziswe ukuba ngaba umntu uneengxaki zezintso okanye usebenzisa isixhobo sokubetha kwentliziyo okanye esinye isixhobo esifakelweyo.

Ngubani ongafanelekanga

I-cranial tomography akufuneki yenziwe kubantu abakhulelweyo okanye abarhanela ukuba bakhulelwe. Kufuneka kwenziwe kuphela xa kukho imfuneko, ngenxa yemitha ekhutshwayo.

Ukongeza, umahluko we-tomography uyaphikiswa kubantu abane-hypersensitivity to umahluko kwiimveliso okanye ukusilela kwezintso.

Iziphumo ebezingalindelekanga ezinokwenzeka

Ngamanye amaxesha, iimveliso ezichaseneyo zinokubangela iimpendulo ezigwenxa, ezinje ngokuqaqanjelwa sisisu, ukungangxami, isicaphucaphu, ukurhawuzelela nokubomvu.
